Abstract (en)
[origin: EP1166937A2] Process for repairing metallic parts of gas turbines comprises: (a) mechanically radiating the surfaces with a non-oxidic jet material; (b) closing open groove ends by build-up welding a welding material relative to the component material; (c) filling the groove closed on one end side with a solder powder with or without a filler; (d) heating the solder powder in a vacuum until it becomes liquid and metallurgically joins with the component material; and (e) removing the solidified solder. Preferred Features: The jet material is silicon carbide. After the solder has been liquefied and solidified in the groove, it is annealed in a vacuum.
